NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented April 30, 1907.

Application filed July 12 1906- Serial No. 325,866.

To all 1077 0771 it may (mince/'11,.-

Be it known that I, ALVA B. COURT, a citizen of the United States andmidshipman in the United States Navy, stationed on board United Statessteamship Pen nsyloan'ia, navyyard, New York city, have invented certainnew and useful Improvements in Non-Refillable Bottles; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertams to make anil' use the same.

This invention relates to improvements in bottles and closures therefor,and especially to that type designated as noi'i-retillable bottles, andthe object of which is apparent.

While I do not limit myself to the specific details shown and described,to more l'ully understand the invention, reference is had to theaccompanying drawings illustrating a practical embodiment of same, inwhich like letters designate the same parts in the several views, and inwhich Figure 1 is a sectional elevation through the top of a portion ofthe bottle, the closing device being shown in elevation. Fig. 2 is asimilar sectional view, the section being taken through the closingdevice also. Fig. 3 is an enlarged detail view showing the position ofthe closing device prior to its biing sprung into the bottle neck. Fig.4 is a sectional view on the line 4 4 of Fig. 1, and F 5 is a section onthe line 55 of Fig. 1.

1 designates the bottle neck provided with the annular shoulders 2, 3,and 1.

5 designates a metal plate which rests on the shoulder 3 and may beblown into the glass, the object of which plate, it employed, being thatthe neck may be severed if acid be used to remove the closing device,the metal plate being of such material as to be affected anddisintegrated by an acid as soon as or before the rest of the device andthe heat produced by the chemical action, locally applied, causing thering to expand and crack the thin glass that surrounds the metal ring.

6 designates the annular valve casing which is adapted to seat on theshoulder 2 when sprung into the bottle neck, which valve casing ismachined as at 7 to seat the valve 8, which valve is provided with ashank 9 recessed as at 10 to receive the end of a coil spring 11interposed between the valve stem 9 and the hollow stem 12 of the valveprotecting cap 13, the said cap being in the form of a cylindrical cupopening downwardly and mounted to be guided within an annular projection14 forming an integral extension of the valve casing 6, which extensionis slotted as at 1.5.

The lower end of the hollow valve shank 12 is guided by the valve stem9, which operates therein, and the spring 11 tends to 'lorcc the cap andvalve apart, the upward movement of the cap being limited by suitablelugs 16 mounted on the inside face of a split cylinder 17 of resilientmaterial, such as spring metal, and this metal cylinder is provided atone edge with a circumfcrentially extcnfling tongue 18 adapted tonormally register with a shallow notch 19 cut in the opposite edge ofsaid cylinder and adapted to also lit an elongated notch 20 so disposedthat the spring cylinder may be forced inwardly until its edges touch,when the cylinder will be disposed spirally, as clearly shown in Fig. 3,in which position the spring cylinder may be clamped by means of a wireor cord 21 'litting within a circum'l'erential groove 22. The lowercasing 6 is also split, as shown clearly in Figs. 1, 3., and 5, and ispreferably provided with a cork gasket 23 which may also extend withinthe space formed by the adj accnt edges 01 the casing.

In operation, the parts are assembled in the position shown in Fig. 3with the spring split ring or cylinder contracted, in which position thetongue 1.8 is seated in the slot- 20 so that the spring cylinder isspirally disposed. WVhen thus interlocked, the wire or cord may besecured thcrearound in the groove 22. After the bottle has been tilled,the closure is forced down through the top, it being understood that inthe contracted state, the diameter oi the split ring or cylinder 17 issuch as to enable its passage ,through the opening at the top of thebottle. After the parts have been fairly started on their way, thestring or wire 21. may be cut, and upon further shifting the partsdownwardly when the upper edge of the cylinder 17 passes beneath theshoulder 4, the spring member or cylinder will expand into the positionshown in Fig. l and interlock the parts in the bottle neck with thetongue 18 disposed opposite the slot 19 so that upon an attempt tocontract the cylinder to withdraw the samc, the attempt will befrustrated by the tongue 18 interlocking in the notch .19, and thusprevent the further con traction of the cylinder. It will also be seenthat the bore of the bottle neck between the shoulders 2 and 3 isconical so as to insure the entrance of the cork gasket and the subsequent compression of the same to make the valve seat tight.

Vith the parts in their interlocked position, it will be obvious thatthe cork having been extracted, upon inverting the bottle the valve 8will be forced outwardly against the compression of the spring 11, andthe contents will flow through the lower valve casing out through theslots 15 into the upper cylinder and thence through the outlet of thebottle, but upon the bottle being again set up, the valve 8 will beagain seated, the protecting cap 13 at all times preventing anytampering with the valve but allowing of the ready outflow of the liquidwhen desired.

Having thus described the invention, what I claim is:

1. The combination with a bottle provided With a recessed portion in theneck thereof, of valve mechanism therefor, and means for holding saidvalve mechanism within said bottle neck, comprising a split resilientring adapted to be sprung in said recessed portion of said bottle neckabove and in operative relation with said valve mechanism, saidresilient ring being provided on its respective adjacent edges with atongue and a nonalined slot su'liiciently deep to receive said tongueand allow the closing of said split ring, substantially as described.

2. The combination with a bottle provided with a recessed portion in theneck thereof, of a valve casing, a valve therefor, a protecting cap forsaid valve, and means for holding said protecting cap within said bottleneck portion of the bottle and having an upward annular extensionprovided with outlet slots, a valve seated in said chamber, a splitcylinder inclosing said annular extension, a protecting cap operatingimmediately above said valve within said annular extension and providedwith a hollow stem, and a spring interposed between said protecting capand said valve, substantially as described.

4. The combination with the bottle provided with a recessed portion inthe neck thereof, of a valve casing, a valve therefor, a protecting capfor said valve, and means for holding said protecting cap and valvewithin said bottle neck, comprising a split resilient ring adapted to besprung in said recessed.

portion of said bottle neck, said split ring he mg provided withinwardly disposed radial p10160b10113 adapted to rest above saidprotecting cap and said split ring being also provided on its adjacentedges With a tongue and slot, substantially as described.

In testimony whereof, I aflix my signature, in presence of twowitnesses.
